Hi All, I have deployed the Openstack using Packstack And I have adjusted the network configuration as follow: IFCFG for external interface on Controller (network node): http://pastebin.com/10MRZiM9 IFCFG for external bridge on Controller (network node): http://pastebin.com/RsXb7wXH IFCFG for internal interface on Controller (network node): http://pastebin.com/jRKRSnc7 IFCFG for internal bridge on Controller (network node): http://pastebin.com/sdNnsi85 Output of ovs-vsctl show: http://pastebin.com/agy1FxDx And I have configured public network in project1 and set it as external (using admin to assign it as external). I have create router1 and assign this network as GWY, and the other as private. I tried to allocate floating IP but I failed. I have checked and I found and I found the GWY port is in the router is down as well. Here is the O/P of neutron: http://pastebin.com/RN49jmkk Can someone tell me what is wrong please? Thanks, Ashraf
